Project Work Day #1 April 12th 2013 DESIGN DAY

Today is your first work day for the green building project. Consult your project guidelines! Your first task is to design the layout and dimenions of your buildings, paying particular attention to passive solar design that takes advantage of light and heat from the sun. Consider how landscaping around your building fits in with passive solar goals.

Project Work Day #2 Heat Loss Calculation (R and U Values)

Today you will learn about R and U values that you will need to complete the calculation worksheet in Part II of the project.
Recommended R-values:
R value of Walls: up to 40
R value of Ceiling: up to 60
R value of Floor: at least 10
Look up R values for Windows and Doors using the links below

Furnace Efficiency AFUE: at least 96 (see Furnaces links below)
If you are interested in taking the concept even further, complete the following steps for extracredit on the project:
1. Diagram a cross section of the following structural parts: Wall, Floor, Ceiling, and Foundation/Basement (if a heated living space), label component parts provide R-values for each part. (See R-value Wall Diagrams and the Buildling Science links below)
Note: If you are having trouble finding an R-value of a specific building material, try googling it. If you still cannot find it, ask me for help.
2. Calculate total R-value of the above structural parts by summing the R-value of the parts. Convert overall R-values to U-values (1/R) (You may want to use the online R-value calculator, see link below.)
3. Choose exterior door and window type and determine R-value and convert to U-value (1/R)
4. Calculate total area (in ft2) of exterior walls, exposed ceiling, exposed floor, exterior doors, and windows.
5. Transfer numbers (U values and area) to Step 1 of the Heat Loss Calculation Worksheet and complete calculations.
